Abstract (en)
[origin: WO0077881A1] A microwave coupler (200) in a multilayer, vertically connected stripline architecture provided in the form of a microwave integrated circuit that has a homogeneous, multilayer structure. Such a coupler has multiple sets of stripline layers separated by interstitial groundplanes (232, 262, 282) and wherein more than one set of layers has a segment of coupled stripline. A typical implementation operates at frequencies from approximately 0.5 to 6 GHz although other frequencies are achievable.
